IMPROVEMENT IN ROTARY CULTIRVATORS.

Specication forming partof Letters Patent No. 183,229, dated October 10, 1876; application filed July 11, 1876.

To all whom it may concern.-

Be it known that I, SEVIER TADLOCK, of Hope, in the county of Lavaca and State of Texas, have invented a new and useful Improvement in Spading-Machine, of which the following is a specication:

Figure lis a side view of my machine, part of the frame being broken away. Fig. 2 is a front view of the same, the frame being shown in section, and part of the 'carrier-trough being broken away.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to furnish an improved machine for opening ditches to drain land and form fences, and to grade railroads, 8vo., and which shall be convenient in use, effective in operation, and of-light draft.

'lhe invention consists in thecombination ofthe stationary spades, the hinged angular ings in the middle parts of the side bars of the frame A revolve the journals of the shaft B, to the center or' which is attached the wheel C. To the rim of the wheel O, at suitable distances apart, are attached cross-spades or cutters D. To one edge of the rim of the wheel C are hinged right-angled spades E, which rest upon the rim of the wheel C, and upon the hinged ends of which are formed arms F, projecting inward and against springs G, attached to the rim of. the wheel C, to hold the spades E upon their seats upon said rim. The spades D and E thus form three sides of a series of rectangular boxes. H is an angular chute, the middle part of which is securely attached to the rear cross-bar of the frame A. The chute H covers the open tops and sides of the boxes formed by the spades- D and E, and its upper end extends to the top of the wheel, and is supported by braces I, extending lto the side bars of the frame A. rlhe lower end ofthe chute H extends to the bottom of the wheel, and cuts the bottom and one side of the slice of soil, the spades D E cutting its other side, and cutting it into cubical blocks. As the machine is carried forward the spades D E carry up the blocks of soil through the chute H. As the loaded spades pass from the upper end of the chute H, the armsF strike the rounded inner end of the frame J of the carrier-troughK, which tilts the spades E, as

shown in Figs. l and 2, and discharges the Aisattached pulley N, around which passes a band, O.` The band 0 also passes around the shaft B of the ditching-wheel C, so that the carrier-screw M may be operated by the advance ofthe machine, to move the soil deposited in the trough K outward, and drop it to the ground at such a distance from the wheel C as to be entirely out of the way. The rear end of the machine is supported by the wheel P, the standard Q of which is attached to the rear cross-bar of the frame A. When the machine is at work it rests upon the spades D E, and

by its weight forces said spades into the ground. When the machine is not at work, its forward partrests` upon the wheels R, which are pivoted to the lower ends of the bars S T. rlhe bars S incline to the rearward, and their upper ends are pivoted to the side bars of the frame A. The bars T incline forward, pass through keepers attached to the side bars of the frame A, and their upper ends arepivoted to the eccentrics U, which are pivoted to thev side bars of the frame A, are provided with springs V to hold them to their places, and shouldv be provided with pawls and ratchets. The wheels R also serve as gage wheels, to regulate the depth to which the spades D E enter the ground.

Having thus described my invention, I claim as new and desire to secure by ,Letters Patent' 1. The combination of the stationary spades D, the hinged angular spades E, provided with the ditching-wheel C D E, the shaft B, with the arms F and springs G, and the and the frame A, substantially as herein chute H, with the wheel C, shaft B,and frame shown and described.
